Intel has issued fresh "microcode revision guidance" that reveals it won’t address the Meltdown and Spectre design flaws in all of its vulnerable processors – in some cases because it's too tricky to remove the Spectre v2 class of vulnerabilities.

The new guidance, issued April 2, adds a “stopped” status to Intel’s “production status” category in its array of available Meltdown and Spectre security updates. "Stopped" indicates there will be no microcode patch to kill off Meltdown and Spectre.

The guidance explains that a chipset earns “stopped” status because, “after a comprehensive investigation of the microarchitectures and microcode capabilities for these products, Intel has determined to not release microcode updates for these products for one or more reasons.”
